MATRIX FILTER FOR CORRECTING EXPERIMENTAL-DATA

The paper presents a filtering algorithm which corrects the results of measurements of certain physical quantities if any additional informa tion about the measured values is known. The algorithm is very effecti ve in one-dimensional as well as in two-dimensional problems where add itional constraints are presented in the form of differential equation s. For example, this technique can be used to correct the measurements of certain dynamic quantities if some information about motion of exa mined bodies is known. It can also be used to correct the strain field measurements if the conditions of continuity of strain field are incl uded.
